Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Memory leak getting orientation and position of HMD

The project I'm working on only needs the tracking information from the HMD and two controllers, not the display functionality of the HMD. To bypass the HMD manually modifying the projection matrix, I am enabling the HMD, grabbing the position and orientation, then disabling the HMD.

 UHeadMountedDisplayFunctionLibrary::EnableHMD(true);
 UHeadMountedDisplayFunctionLibrary::GetOrientationAndPosition(_hmdRotation, _hmdPosition);
 UHeadMountedDisplayFunctionLibrary::EnableHMD(false);

Definitely a hack, but I don't have the time to track down where in the engine the HMD is modifying the projection matrix. The memory leak I'm experiencing is approximately 6MB every time I run the code above. I've also tried forcing garbage collection and only running the code above 5 times per second with no success.
